PILING- DEVICE.

Specification of Letters latcnt.

Patented Mar. 8, 1921.

To all whom it may concern:

Be it known that we, WILLIAM H Ron- ERTSON and FREDERICK WV. FISHER,c1t1zens of the United States, and residents of New Milford, county ofLitchfield, and State of Connecticut, have invented an Improvement inPiling Devices, of which the following is a specification.

The object of this invention is to prov de a simple and practicalmachine for p1l1ng cloth or other materials in rope form into bins foraging or other purposes after having been subjected to priortreatmentsuch as boiling in connection with the bleaching operations.More particularly, the invention is intended for handling cloth in ropeform received from the boiling keir of a bleacher and piling the sameinto bins for agmgand in which the rope-like material is laid in azigzag form so that in being lald the strand of rope-like form is causedto lie across itself in what may be called a more or less criss-crossarrangement, and thereby providing air spaces through the piling fabricand which facilitates the aging operation.

The general construction of the improvement comprises an upright tubularguide universally jointed at the top to a suitable support and throughwhich the rope-like fabric is guided downward, being fed into the upperend of the tubular guide by suitable guide means such as a groovedwheel, said tubular guide being combined with means arranged at ,rightangles to each other for impartin thereto a reciprocating motion,whereby t e two motions at substantially right angles cause the tubularguide to swing into various oblique positions, the means for impartingreciprocation in one direction giving a relatively lesser number ofreciprocations than are imparted by the reciprocating means for givingmotion in the other direction, with the result that the lower guidingend of the tubular guide is caused to traverse back and forth in azigzag manner where there may be, for example, nine completereciprocations in one direction to one reciprocation in the otherdirection with the result that the rope-like cloth is laid back andforth along the length of the bin with the strands of each layercrossing the strands of the previous layer.

The invention further compreliends details of construction whichtogether with the features above stated are more fully describedhereinafter and pointed out in the claims.

The invention will be better understood by reference to the drawing inwhich is shown a perspective view illustrating the general elementswhich enter into the construction.

2 is the upright tubular guide for the cloth in rope form. This tubularguide may be formed of wood or metal, as preferred, and is hung at thetop upon a universally jointed support 3 connecting it with a joist orsuitable stationary part I of the building, from which it will beunderstood that the said tubular guide may be swung in any direction atits lower and free end which is arranged above the bin 27, so that theropelike fabric 6 which passes down through the guide may be deliveredinto the bin as hereinafter more fully explained. 5 is a grooved wheelover which the cloth rope 6 passes and from which it is guided downwardinto the open end of the tubular guide 2, the said guide wheel 5 beingarranged close to the upper end of the guide 2 and relatively close tothe universally. jointed support 3. 7 is a weighted rollerwhich restsupon the fabric in the groove of the guide wheel 5 to in sure its beingproperly guided therein, and said wheel 7 is journaled in an arm 8pivoted relatively to the joist or stationary frame 4, whereby theweighted roller 7 may continually rest upon the rope-like fabric whileat the same time having more or less freedom to adjust itself to anyirregularities in the thickness thereof.

9 is a horizontal shaft carried in suitable bearings 10 which may besuspended by any suitable hangers which are commonly employed infactories. At one end of the shaft 9 is arranged a crank wheel 11 havingthe crank pin 12 and at the other end said shaft is provided with abevel gear 25. A second horizontal shaft 17 similarly supported injournal bearings 18 is provided at one end with a bevel pinion 24meshing with the bevel gear 25 of the other shaft and has its other endprovided with a crank wheel 19 having a crank pin 20. The shaft 17 isalso provided with fast and loose pulleys 26 adapted to be driven by apower belt for putting the shafts 9 and 17' into motion or forpermitting them to come to rest according as to whether the belt isshifted to the fast or to the loose pulley, such featuresbeing wellknown in factory equipments, and will need no further description.

As will be seen, the crank wheel 11 provides a much greater throw to thecrank pin 12 than is obtained by the crank wheel 19, but on the otherhand, the crank wheel 19 will make a greater number of revolutions perminute than will be made by the crank wheel 11. The crank pin 12 hasjour' naled to it a block 16 and to this block is hinged a connectingrod 13 whose other end is connected to a block 15 hinged to a band 14surroundingthe tubular guide 2, at some distance from its pivotalsupport 3. The blocks 15 and 16 provide universally ointed connectionsbetween the crank pin 12 and the band 14 of the guide 2, so that whilemaking a direct thrust or pull between the crank pin and the tubularguide, the latter may be shifted at substantially right angles to saidthrust or pull. Similarly the crank pin 20 is connected with the band 14of the tubular guide by means of a connecting rod 21 which has universaljointed connections 22 with the band and 23 with the crank pin, so thatit may impart a direct thrust or pull while at the same time permittingthe transverse swinging by the crank pin 12 and rod 13. As the crankwheel 19 makes so many more revolutions'than the crank wheel 11, it ismanifest that the tubular guide 2 will reciprocate in its swingingmotion many times in one direction relatively; to each reciprocation inthe other direction. Thus, the reciprocations of the guide 2 under theaction of the crank wheel 11 is represented by the double pointed arrow00 y, whereby with this single reciprocation by the crank 11, the

guide is given 10 reciprocations in the other direction as indicated bythe dotted lines 8 29 arranged in the bin 27. In making thesereciprocations s t, a series of reciprocations will be made when theguide 2 traverses in the direction of the arrow y and then a secondseries of reciprocations s 25 will be made when the tubular guide 2reciprocates in the direction of the arrow as, and these two sets ofreciprocations s t will alternate in position and will cross asindicated by the dotted lines, as shown. It is manifest, therefore, thatthe fabric in rope form will be laid in the bin in the zigzag crossingform, as shown by these dotted lines .9 t and following the direction ofthe arrow heads placed thereon, so that each zigzag strand crosses thepreviously laid zigzag strand tails may be changed or modified innumerous ways While maintaining the same operations upon the guidingmeans for the fabric, it being understood that the essential featureinthepreferre'd form of the invention resides in providing a guide forthe fabric having a relatively fixed position and a movable guide'forthe fabric adjacent to the bin and combined with means for imparting toit a greater number of reciprocations in one horizontal direction thanare imparted to it in a transverse direction. lVlore'gcnerically stated,the invention may be considered as embodying a fabric guide combinedwith means to reciprocate it in a horizontal direction in two directionsand in which the reciprocations in one direction are relatively greaterthan the reciprocations in the other direction in any given period oftime, and in which further suitable provision is made for guiding thefabric to the upper portion of ithe reciprocating fabric guide, wherebythe fabric may be properly fed into and piled in the bin.

It will now be apparent that we have devised a novel and usefulconstruction-which embodies the features of advantage enumerated asdesirable, and while we have in the present instance shown and describedthe preferred embodiment thereof which has been found in practice togive satisfactory and reliable results, it is to be understood that wedo not restrict ourselves to the details, as the same are susceptible ofmodification in various particulars 'without departing from the spiritor scope of the invention.

Having thus described ourinvention, what we claim as new and desire tosecure by Letters Patent, is

1. A piling machinecomprising a receptacle for receiving the piledmaterial, a substantially fixedly positioned guide for guiding thematerial in strandor rope form to the receptacle, movable means throughwhich the'material is guided arranged between the fixedly positionedguide and the receptacle, and power means for imparting reciprocatingmotions transversely to the movable guiding means, said motions being atsubstantially right angles and the reciprocations in one direction beinggreatly in excess of the reciprocations in the other direction.

2. The invention according to claim 1,

wherein the movable guiding means consists of a long upright tubularguide pivoted on a universal joint adjacent to the fixedly p0- sitionedguide and having its lower end movable over the receptacle.

3. The invention according to claim 1, wherein the power means forreceiprocating the movable guiding means comprises two cranks geared torotate in planes substantially at right angles to each other and one ofthe cranks rotating with a greater number of revolutions than the other,and connecting means from the respective cranks to the movable means forguiding the material.
